Don’t know if Peru has the death penalty, but read that in 2006 they were considering it for rape. If so, then one would think they would now have it for murder AND rape.
I don't believe any SA country has the DP (except for Guyhana (sp?)), for anything other than terrorism and treason. It's tough to do away with capital punishment for treason when the military coup is a staple commodity of the entire continent.
I'm fairly confident Peru does not have capital punishment for just murder.
